![\large\boxed{x=-\sqrt{10}\ or\ x=\sqrt{10}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%3D-%5Csqrt%7B10%7D%5C%20or%5C%20x%3D%5Csqrt%7B10%7D%7D)
Step-by-step explanation:
![x^2=10\iff x=\pm\sqrt{10}](https://tex.z-dn.net/?f=x%5E2%3D10%5Ciff%20x%3D%5Cpm%5Csqrt%7B10%7D)
The graph represents a parabola and a parabola is maximum or minimum at its vertex . So we need to check the graph , and find the point where the graph is maximum or minimum. And from the given graph , we can say that it is a downward up parabola which is minimum at its vertex . And the minimum point is (1.4). So the vertex is (1,4) .
All you need to do is multiply 3 yards by 10 yards to get 30 square yards.
